Hi.
I have started to do this question (the question it's self is attached with it's relevant diagrams) but I am coming up with a too large a maximum design load, the value I am looking for isn't on the tables I have so I must have made a calculation error somewhere. Any help would be much appreciated.
Here is what I have so far:
Volume of concrete slab= (6x6x0.175)=6.3m^3
Volume of reinforcement= 6.3 x 1.25% = 0.07875m^3
Total Volume= 6.37875m^3
G=(6.3x24.0) + (24.0 + 0.04725 x 0.07875)
=153.09kN/m^3
Q= 2.8 kn/m^3 given with the question
WL^*=(1.2G+1.5Q)x span x spacing
=(1.2x153.09+1.5x2.8)x6x3
=3382.34 kN
Which is a rather large number so I must be going wrong somewhere.
